Milwaukee — Wisconsin Gov. Scott Walker has fired a campaign aide for making demeaning comments about Hispanics on social media.

Walker dismissed Taylor Palmisano as his campaign's deputy finance director Tuesday. The Republican governor made the move after The Milwaukee Journal Sentinel contacted his campaign about the Twitter posts.

In a March 2011 tweet, Palmisano said she wanted to choke a noisy library custodian whom she described as an "illegal mex." Two months earlier she had complained on Twitter that among fellow passengers on a bus "Nobody speaks English & these ppl don't know how 2 control their kids."

Walker is up for re-election in 2014 and has emerged a potential presidential contender in 2016.

The Milwaukee Journal Sentinel reports that in August, Walker removed Steven Krieser as his assistant deputy secretary at the state Department of Transportation after the Journal Sentinel contacted his office about Krieser's Facebook posts likening illegal immigrants to Satan in an extended rant.
